Urban VI was elected by French Cardinals at the behest of a Roman populace which demanded that an Italian once again sit on Peter's throne. This would not prove to be a good choice for them because Urban really wanted to reform the clergy - in particular, he wanted to limit the extravagant lifestyles which the cardinals had come to enjoy.
Unfortunately, he did not go about these reforms with much tact and his insults and abuse of the cardinals caused them to elect an antipope, Clement VII - this inaugurated the Great Schism of the West. This would last for some 60 years, with one set of popes settled in the Lateran Palace in the Vatican and a second line of popes based in Avignon.
Urban launched upon a program of violence against those he thought to have been conspiring against him, imprisoning people at will and mistreating them brutally. Later historians have considered seriously that he might have been insane.
